TV-Receiver Immunity Evaluation Based upon Rejection of Undesired Signals at Input Tenninals

Some of the results of TV-Receiver CS04 tests performed at the Department of Communications Engineering Laboratory in Ottawa, Canada, are presented. The tests were performed usingrandomly available receivers (mostly 20-in color sets, different makes) in the rental market. No set tested was immune to levels of out-of-band input signal such as are likely to be encountered in their normal environment due to the emissions of licensed transmitters.
